RHESSys Modelling

Regional Hydro-Ecological Simulation System

RHESSys is a GIS-based, hydro-ecological model which has been developed to simulate water, carbon and nutrient flux cycling and transport in watersheds (Tague and Band 2004). RHESSys combines both a set of physically based process models and a methodology for partitioning and parameterizing the landscape.

The model is designed as a spatially nested hierarchical representation of the landscape, using different models to represent processes at different scales.
